Assembly: System.Web (in System.Web.dll)
| Name | Description | |
|---|---|---|
![]() | DataBindingHandlerAttribute() | Initializes a new instance of the DataBindingHandlerAttribute class using no parameters. This is the default constructor. |
![]() | DataBindingHandlerAttribute(String) | Initializes a new instance of the DataBindingHandlerAttribute class with the specified type name. |
![]() | DataBindingHandlerAttribute(Type) | Initializes a new instance of the DataBindingHandlerAttribute class of the specified Type. |
| Name | Description | |
|---|---|---|
![]() | HandlerTypeName | Gets the type name of the data-binding handler. |
![]() | TypeId |
| Name | Description | |
|---|---|---|
![]() | Equals(Object) | This API supports the product infrastructure and is not intended to be used directly from your code. Determines whether two object instances are equal.(Overrides Attribute.Equals(Object).) |
![]() | GetHashCode() | This API supports the product infrastructure and is not intended to be used directly from your code. Returns the hash code for this instance.(Overrides Attribute.GetHashCode().) |
![]() | GetType() | |
![]() | IsDefaultAttribute() | When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute.) |
![]() | Match(Object) | When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.) |
![]() | ToString() | Returns a string that represents the current object.(Inherited from Object.) |
| Name | Description | |
|---|---|---|
![]() ![]() | Default | Defines the default attribute for the DataBindingHandlerAttribute class. |
| Name | Description | |
|---|---|---|
![]() ![]() | _Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr) | Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.) |
![]() ![]() | _Attribute.GetTypeInfo(UInt32, UInt32, IntPtr) | Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.) |
![]() ![]() | _Attribute.GetTypeInfoCount(UInt32) | Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.) |
![]() ![]() | _Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr) | Provides access to properties and methods exposed by an object.(Inherited from Attribute.) |

The following code example defines a data-binding handler, named MyDataBindingHandler, to be used by the designer in editing mode. On exiting the editing mode, the Text property value is displayed.
using System; using System.Collections; using System.Web.UI; using System.Web.UI.Design; using System.Web.UI.WebControls; using System.ComponentModel; using System.ComponentModel.Design; namespace CustomControls { [ DataBindingHandler(typeof(MyDataBindingHandler)), ToolboxData("<{0}:MyLabel runat=server></{0}:MyLabel>") ] public class MyLabel : Label { public MyLabel() { // Insert your code here. } } public class MyDataBindingHandler : DataBindingHandler { public override void DataBindControl(IDesignerHost host, Control control) { ((Label)control).Text = "Added by data binding handler."; } } }
